AC in 2015 Rogue

I have a 2015 Rogue. I’m unsure if I’m under
warranty still. The dealership mechanics were just
awful so I stopped using them.

Every summer (I’m in Southern California) my AC
has issues. The first 2 years I owned it I brought it
to Nissan and of course they found nothing wrong.

But once it starts getting hot (80/90/100 degrees
outside) I’ll run the AC with the recycle air button
on. It blows nice a cold. After about 5/10 mins the
recycle button automatically shuts off and blows
hot outside air. I hit the recycle button again and it
takes 5/10 mins of hot smelly HOT LA smog air  
before blowing cool again. Then the process
repeats. 5/10 mins of cool then steaming hot.

I have kids and they just sweat I had a kid throw
up from the heat.

The dealership had said they found nothing wrong.
And this doesn’t happen in the winter.
